Product Range Summary
Pneumatic Audible Devices can be used in a wide variety of industrial environments
Particularly where pneumatics are preferred to electrics or electronics in hazardous areas as alternatives to horns, klaxons, sirens, whistles
Although designed for mounting into a control panel, the materials of constructions make the devices suitable for many applications in exposed conditions
Also available: Ancillaries, Signal Towers & Complete Compressed Air or Electro-Pneumatic Systems

Utilisation - Main Applications
Applications
Virtually every type of industry has processes that include at least one of the categories of Alarm, Annunciation, Signalling & Indication; here are some typical examples:
Alarm & Annunciation
Instrument panel, signal tower or complete alarm control system. Generally, this area of application covers the deviation of parameters from a set point to a critical level:
High & Low warnings – liquid & materials levels, flow, pressure, temperature, time, speed, Fire & overheat detection Flooding
Signalling
In some industries, an audible signal is preferred to a visual, especially over distances and where operators are working at remote points:
Starting and stopping of an operation Movement of transport or equipment Machine and conveyor malfunction or stoppage Flowline production Personnel call systems
Indication
Prior knowledge of an impending condition which will require attention is often required:
Monitoring of vital sections of power and production plant
Falling pressure in gas bottles, Diesel engine monitor panels Gas leaks, Pressure drop across filters
Design & Development
Continuous Improvement Programme
New devices are always in the pipeline:
*** Lower & Higher Pressure Models
*** Din Rail Mounted Devices
*** Control Valve Mounted Devices
*** Combination Audio & Visual Indicator
*** Motorised ‘Spinning’ Units
*** Acoustic Sensor Device
Special Assembly Configurations
Subject to quantity it is possible to manufacture other types of Pneumatic Audible Devices: Optional body materials and air supply connections, tailormade bodies, i.e. with flanges, multi-assemblies, i.e. 4-unit cluster
Complete Systems
Design and build of purpose-made systems can be undertaken, from simple locally fitted boxes to complex multi-point annunciator channels and signal towers

Operation - Instructions & Test
***IMPORTANT*** NEVER use Pneumatic Audible Devices in close proximity to the human ear
All Audible devices are sealed units and NO attempt should be
made to dismantle as permanent damage will result
